Starting in 2011, energy suppliers in Germany will be required to offer electricity at variable rates under the German Energy Act. A new energy management software platform will enable customers to opt for flexible electricity rates, so that they can purchase power at times when it is available more cheaply. Another advantage is better utilization of the power grid.

Stanford engineers have discovered a process called photon enhanced thermionic emission (PETE) that simultaneously combines the light and heat of solar radiation to generate electricity, and could offer over double the efficiency of existing solar cell technology. The process could reduce the costs of solar energy production enough for it to compete with oil.
